[0033] The specific embodiments of the present application provide a PCIE card tail fixing structure, as shown in Figure 1 which comprises a fixed part 11 and a movable part 12 rotatably connected with the fixed part 11; the fixed part 11 is provided with a first guide limiting piece 111 corresponding to the width direction of the PCIE card 100, and the movable part 12 is provided with a second guide limiting piece 121 corresponding to the width direction of the PCIE card 100; the structure further comprises a quick release structure 13 for locking the movable part 12 and the fixed part 11 together; during installation, the tail of the PCIE card 100 is slid to the position along the side of the first guide limiting piece 111, the movable part 12 is rotated to the locking position, and the movable part 12 and the fixed part 11 are locked together through the quick release structure 13.

[0034] The first guide limiting piece 111 and the second guide limiting piece 121 can limit the width direction of the tail of the PCIE card 100, and the quick release structure 13 is used to lock the movable part 12 and the fixed part 11 together, which ensures the structural stability in the locked state and avoids the use of traditional plastic elastic structure or screw method for locking. When it is necessary to dismount the PCIE card 100, the movable part 12 is unlocked from the fixed part 11 by pressing the quick release structure 13, and then the PCIE card 100 can be dismounted without using dismounting tools, which is convenient to use.

[0035] In some embodiments, as shown in Figures 1-3 The first guide limiting member 111 is provided with a first guide slot 1111, and an end of the first guide slot 1111 away from the movable part 12 is provided with a first limiting part 1112 for limiting one end of the tail part of the PCIE card 100. The second guide limiting member 121 is provided with a second guide slot 1211, and an end of the second guide slot 1211 away from the fixed part 11 is provided with a second limiting part 1212 for limiting the other end of the tail part of the PCIE card 100.

[0036] The first guide slot 1111 and the second guide slot 1211 are both horizontally arranged, and when the movable part 12 is rotated to the locking position, the second guide limiting member 121 and the first guide limiting member 111 are at the same height. In this way, the PCIE card 100 can be conveniently slid into the fixed part 11 in a side-sliding manner. In order to limit the sliding direction of the PCIE card 100, the first limiting part 1112 and the second limiting part 1212 are provided, and after the PCIE card 100 is installed, the first limiting part 1112 and the second limiting part 1212 are just at the two ends of the tail part of the PCIE card 100, thereby playing a limiting role.

[0037] It should be noted that the end of the first guide slot 1111 and the second guide slot 1211 close to each other is in an open state, which can enable the plate along 110 of the PCIE card 100 to be simultaneously in the first guide slot 1111 and the second guide slot 1211.

[0038] In some embodiments, the first limiting part 1112 and the second limiting part 1212 are respectively part of the first guide slot 1111 and the second guide slot 1211. Of course, in other embodiments, the first limiting part 1112 and the second limiting part 1212 are respectively independent components of the first guide slot 1111 and the second guide slot 1211, and are only installed in the corresponding positions when in use.

[0039] Preferably, in order to improve the applicability of the PCIE card tail part fixing structure 1, which can be applicable to PCIE cards 100 of various models, the first guide limiting member 111 and the second guide limiting member 121 are independent components, i.e., the first guide limiting member 111 and the second guide limiting member 121 are installed in the corresponding positions when in use, and generally can be installed by screws. The first guide limiting member 111 and the second guide limiting member 121 can be selected according to the model requirements of the PCIE card 100.

[0040] More preferably, the fixed part 11 and the movable part 12 are provided with card holes of different heights, and the first guide limiting member 111 and the second guide limiting member 121 can be installed in the card holes of different heights of the fixed part 11 and the movable part 12 according to different height installation requirements.

[0043] In some embodiments, the rotatable connecting structure 14 further comprises a torsion spring installed on the rotating shaft 143. The torsion spring can exert a spring force on the movable part 12. When it is needed to detach the PCIE card 100, the quick release structure 13 is pressed, and the movable part 12 is quickly opened away from the PCIE card 100 under the action of the spring force of the torsion spring, so that more rapid detachment can be achieved.

[0044] As shown, Figure 3 The quick release structure 13 comprises an elastic sheet 132 arranged on the fixed part 11 and a clamping groove 131 arranged on the movable part 12. The elastic sheet 132 is located on the top edge of the fixed part 11, and the elastic sheet 132 is provided with a protrusion 1321 which is matched with the clamping groove 131.

[0046] As shown, Figure 6 , 7 As shown, Figure 7 The PCIE card 100 is installed in the installation cavity. At this time, the plate along 110 of the PCIE card 100 is clamped in the first guide groove 1111 and the second guide groove 1211. Since the first guide groove 1111 can play a role in limiting the PCIE card 100 in the transverse direction, and the quick release structure 13 is arranged to lock the movable part 12 and the fixed part 11 together, the structural stability in the locked state is ensured, and the traditional plastic elastic structure or screw mode is avoided to be used for locking.

[0047] The embodiment of the present application further provides a quick release method, which is used for the PCIE card fixing device. The method comprises the following steps:

[0048] First step: pressing the quick release structure, so that the locking state of the movable part and the fixed part is changed into the unlocking state.

[0049] The second step is to rotate the movable part to the direction away from the PCIE card to release the limitation of the second guide limiting part on the PCIE card.

[0050] The PCIE card can be detached by pressing, which is convenient to use.

[0051] In conclusion, the PCIE card tail fixing structure comprises a fixed part and a movable part, the movable part is rotationally connected with the fixed part, when the movable part is rotated to a locking position, the first guide limiting part and the second guide limiting part can limit the width direction of the PCIE card tail, and the quick release structure is adopted to lock the movable part and the fixed part together, which ensures the structural stability in the locking state, avoids the use of traditional plastic elastic structure or screw mode for locking, when the PCIE card needs to be detached, the quick release structure is pressed to release the locking of the movable part from the fixed part, and then the PCIE card can be detached, without the use of a removal tool, which is convenient to use.
